So my somewhat nutty whippet is nearly 8 months old and has suddenly started chewing things he hasn't touched before, even as a baby puppy. In the last couple of weeks he's had a go at skirting boards and a TV cabinet and I've caught him having a nibble in kitchen chairs 
Some internet research has revealed that thete may be a second teething stage that can happen around this age. I'm trying to make sure he has things to chew on like pigs ears, antlers etc and am trying to deter hi from chewing but it's a bit disheartening to cone home and wonder what he had destroyed that day.
